Summary
Red Hat Security Advisory: openstack-swift security update

Notes

Topic
Updated openstack-swift packages that fix one security issue are now available for Red Hat Enterprise Linux OpenStack Platform 3.0. The Red Hat Security Response Team has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.
Details
OpenStack Object Storage (swift) provides object storage in virtual containers, which allows users to store and retrieve files (arbitrary data). The service's distributed architecture supports horizontal scaling; redundancy as failure-proofing is provided through software-based data replication. Because Object Storage supports asynchronous eventual consistency replication, it is well suited to multiple data-center deployment. A timing attack flaw was found in the way the swift TempURL middleware responded to arbitrary TempURL requests. An attacker with knowledge of an object's name could use this flaw to obtain a secret URL to this object, which was intended to be publicly shared only with specific recipients, if the object had the TempURL key set. Note that only setups using the TempURL middleware were affected. (CVE-2014-0006) Red Hat would like to thank the OpenStack Project for reporting this issue. Upstream acknowledges Samuel Merritt of SwiftStack as the original reporter. All users of openstack-swift are advised to upgrade to these updated packages, which correct this issue. After installing this update, the OpenStack Object Storage services will be restarted automatically.
